All oil paintings have been freshly cleaned and treated as necessary. We do not restore works on paper; however, all framed pieces have UV blocking glass and are housed in archival materials. Due to the age of our fine art, there is some wear to be expected. Most gessoed frames will have some losses consistent with age, and gilded frames will likely have areas of bole and gesso exposed.

This is natural and part of the history and beauty of older work. All fine art from Geddes & Di Folco has been thoroughly examined and is stable and in optimal condition unless otherwise stated in the listings. The pieces we sell are original and made by artists and craftspeople, and so there are imperfections to be expected.
